Update for you all. I forced systemd down to the 16.04 version, reconfigured it and it was happy. As for upgrading it to the 18.04 version, YOU MUST PURGE THE ENTIRE /usr/lib/tempfiles.d/ DIRECTORY. One I did that, even thought the install will fail, I was able to get systemd reconfigured. It now properly responds to dpkg --configure commands and the system is no longer in a broken state.
As for how to resolve this upstream, I have a felling this has to do with how WSL handles systemd (as, it doesn't, because WSL ignores systemd for the most part.) most likely related to the fact that we're not working with kernels, and systemd doesn't have anything to hook into during the upgrade. If you're having trouble with a system you forced to the 18.04 beta let me know as I'm going to write a script here in a second to resolve the issue for you. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1748659 Title: Windows 10 Ubuntu 16.04 upgrade to 18.04: package systemd 235-3ubuntu3 failed to install/upgrade: installed systemd package post-installation script subprocess returned error exit status 1 Status in systemd package in Ubuntu: Confirmed Bug description: This was fresh Ubuntu 16.04 instance on Windows 10, running inside a Virtual Box on an iMac.
